Edmund Xie studied law at the University of Victoria (on Vancouver Island, BC, Canada) where he received several awards, including prizes in intellectual property law research and contracts.  In summer 2008 (i.e., the second summer of law school), Edmund worked as a summer student at Smart & Biggar's Vancouver Office, where he was introduced to the practice of intellectual property law for the first time, working under the supervision of several lawyers/patent agents, including Brian Kingwell, Andris Macins, Graham McKinnon, Jeff Morton and Tim Lo. 

After graduating from UVic Law in 2009, Edmund completed PLTC in Victoria and articled with Oyen Wiggs Green & Mutala LLP ("Oyen Wiggs") in Vancouver.  After being called to the Bar of British Columbia in 2010, Edmund continued to work at Oyen Wiggs as an associate from 2010 to the end of 2014.  Edmund worked on many interesting patent and trademark files and gained experience in intellectual property law practice through the guidance and mentorship of many of the lawyers at Oyen Wiggs, including Gerry Oyen, Blake Wiggs, Bruce Green, Cathie Mutala, David McGruder, Tom Bailey, Gavin Manning, George Kondor, Hilton Sue, Craig Ash, Todd Rattray, Richard Johnson, David Takagawa, Amy Fong, Jennifer Marles and Jeff Robinson.  Thanks to all their help and the conducive work and learning environment at Oyen Wiggs, Edmund took and passed the notoriously difficult Canadian patent agent exam on his first try and became a registered patent agent in 2011. 

Since starting his own intellectual property law firm in the beginning of January 2015, Edmund has provided intellectual property law services to clients in many diverse industries, including biotech and pharmaceutical companies, personal care and consumer goods companies, fashion boutiques, wineries, restaurants, internet start-ups, smartphone app developers, and individual inventors.
